What Will You See After an Air Bag
Inates?
After an air bag inates, it quickly deates, so quickly that
some people may not even realize the air bag inated.
Some components of the air bag module – the steering
wheel hub for the driver’s air bag, or the instrument panel
for the right front passenger’s bag – will be hot for a short
time. The parts of the bag that come into contact with you
may be warm, but not too hot to touch. There will be
some smoke and dust coming from the vents in the
deated air bags. Air bag ination doesn’t prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.
{CAUTION:
When an air bag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can’t get out of the vehicle after an air bag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.

children or others could be badly injured or
even killed. Do not leave the keys in a vehicle
with children.

smell CO. It can cause unconsciousness and
even death. If you must drive with the liftgate
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeAutomatic Climate
Control System on page 3-19.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-33.To unlock the liftgate, press the unlock button on any of
the power door lock switches or the remote keyless

{CAUTION:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat
and suffer permanent injuries or even death
from heat stroke. Never leave a child, a
helpless adult, or a pet alone in a vehicle,
especially with the windows closed in warm or
hot weather.
2-14

Power Windows
The controls for the power windows are located on the
armrest on each of the side doors. The switches
operate the windows when the ignition is in RUN,
ACCESSORY or when Retained Accessory Power
(RAP) is active. See “Retained Accessory Power” under
Ignition Positions on page 2-19.
The driver’s door also has a switch for each of the
passenger’s windows.

the top of the switch to raise the window.
Express-Down Windows
The driver’s and front passenger’s window switches
have an express-down feature that allows you to lower
the window without continuously pressing the switch.
Press the top of the window switch down fully to activate
the feature. Lightly tap the switch to open the window
slightly. The express-down feature can be interrupted at
any time by pulling up on the top of the switch.
